Hudy Aluminium Ultra-Light Pinion Gear - Hard Coated - 42T / 64DP

The Hudy Aluminium Ultra-Light Pinion Gear 42T / 64DP (part DY294142) is a high-strength, hard-coated pinion engineered for precision drivetrain efficiency. Machined from premium 7075‑T6 aluminium, it delivers an ultra-light rotating mass while maintaining the durability needed for high-performance RC applications.

Created on a dedicated gear machine, this 42‑tooth, 64DP pinion features ultra-precise tooth shaping and ultra-true running to help achieve smooth, vibration-free operation. Fine internal threading enables easy installation, and the tooth count is clearly etched for quick identification at the track or bench. Each gear is manually inspected and individually run-in to meet Hudy’s stringent quality standards.
